QUART mamFS
Universal Mammography Test Phantom
MODE OF OPERATION
QC tests are carried out at initial equipment installation to establish a visual reference. On a regular routine basis, they are meant to ensure the constancy of the system‘s imaging capabilities.
Any deterioration in imaging performance is revealed by the visual evaluation of the test images. The evaluation of grey values, as traditionally required for conventional x-ray technology, is carried out using a densitometer.
A simple assessment of image quality for digital mammography systems is also possible.
